Sql Server - How To Determine Which Table Of A Multitable View Are Updatable
Jun 29, 2010
Update: My problem doesn't seem to be with the SQL server. I executed an update statement inside the database manually against the view and I was able to update the Bar table. I'll close this and research the OleDbDataAdapters more since I think the problem lies with them.This question applies to MS SQL Server 2000. How do I determine which table of the multitable view can be modified?
[Code]...
I realize I can write two update statements one for each table. My concern is different. I need to audit code that uses views like the one above and does updates on the views. I was hoping to find a way to determine which parts of the updates will be silently ignored.
I edit Bar.Column1 and then call the Update() method of the OleDbDataAdapter. This results in the Bar table not being modified nor is an exception thrown. If I edit Foo.Column2 then call Update() the Foo table does get modified.

We are doing a project using VB2010 as front end SQL server 2008R2 as backend.We need the code to display all the images in thumbnail view in VB when we open a database table.
Masters of the visual basic arts, I, a lowly noob, would just like to ask for your wisdom (and mercy). For my program needs to determine if the data grid view has any content because if that certain datagridview doesn't contain anything, then I would disable a couple of functions for the program.
I have an application that is running fine. I just want to add the auto update feature in that application so that the application can automatically download the updates and install it on the computer.
I am putting together a very simple GridView, one of the columns is a CheckBox.I would like the checkbox to update the SQL table as it is checked, the field in my database is a bit field.Currently i have the following:
This allows the Checkbox to be checked and unchecked however it does not update my SQL Database. I have tried a couple of things but can't seem to get this to work. I am assuming i'd need to write a custom bit of VB around the 'OnCheckedChanged', i do not want an edit button on the page!
I know I've banged heads with this error before, but before the reason was because of my IMEX setting. This is the reason why I made two connections to the spreadsheet, one that uses IMEX=1 for the SELECT query and one with that option removed for the UPDATE / INSERT queries. So now I'm stumped why this is breaking in the following [code].....
Is there an issue with trying to open the same spreadsheet with two connections (I thought I had done this before)? Or some other issue that is causing this error to be thrown? BTW, I'm using this in a vb.net program so I don't think the issue is related to the security issues that asp users usually face with this error... On the other hand, I'm also on Win 7 and I know that its security is much tighter than on XP where I've used other programs that also update an Excel spreadsheet. I wouldn't think so, but would I have to run this in administrator mode in order to update the spreadsheet?
I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
I have a program that copies files to several servers in succession. If one of those servers is unavailable for any reason, my program hangs for about a minute before it continues on to the next server. Is there a quicker way to determine if the path is available or not?
I have a query that I have to run that requires me to get rows from a table based on the value of a field in another table (which I have gotten earlier). I currently have it done like this (simplified).
I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I want to filter the SQL Compact Database to get rows that as been synchronized to the SQL SEVER Using sync framework can any one give me an hint on how to get this done. I will prefer a sample code in VB.NET
I tried Firebird with .NET Provider yesterday. Firebird was sure to beat SQL Compact Edition. I was amazed from it's features and precision. But I felt sad when I wasn't able to find updatable RecordSet/ResultSet features and functions in the .NET provider. FBResultSet doesn't contains anything, no rows addition, creation, modification, nothing. Anybody knows if this feature exists in Ado .Net provider of Firebird because there's no documentation.I would like to receive help because I am waiting to integrate Firebird in my freeware application.Also, if there's are replacement functions for implementing updatable RecordSet, ResultSet.
I'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.

I have to develop a small app for which I have to create a user control which is intended to be something like a Table View.On Form Load, the user should be asked about the number of rows of columns required on the form.Once the user sets the number of cells, each cell should have a button and a Text Box inside it (grouped together).
